velveeta cheese - cut thick
shredded cheddar cheese
taco seasoning mix ( i use mild)
Cook macaroni according to directions on box, and drain - leave in colander
Add milk, velveeta and 2/3 cups of the shredded cheese to the pot you boiled your macaroni in, melt cheese under low heat - I usually salt and pepper the milk and cheese mixture a little bit.
Add the macaroni back into the milk and cheese mixture, Stir and take off the heat. Cover
Brown your ground beef, add the taco mix and water, stir and simmer for 10 minutes - or until it thickens slightly - Turn off the burner and let sit
Grease a 8x8 or larger baking dish with margerine or butter, add your macaroni and cheese
Put a flour tortilla over it -- you can section the tortilla rounds to fit the dish you are using
Add the hamburg/taco mixture and the salsa
Sprinkle shredded cheese over the mixture - reserving some shredded cheese for the top
Add another tortilla to cover the mixture
Cover with shredded cheddar and bake in a 375 degree oven for 20 minutes or until the cheese is melted and the tortilla is browning.
